Which Southeast state has the best solar incentives in 2026?

South Carolina leads the Southeast with its unique 25% state income tax credit (up to $3,500/year, 10-year carry-forward) stacking with the 30% federal ITC. Charleston and Columbia buyers can achieve 7–10 year paybacks after the full credit stack — the fastest in the region. North Carolina is the best large market for buyers without sufficient SC state tax liability. Virginia's VCEA-protected net metering makes it the most policy-stable Southeast choice.

What is Georgia Power's 10 kW solar threshold?

Georgia Power customers receive retail-rate net metering credit (~$0.12/kWh) for solar systems up to 10 kW, but receive only avoided-cost compensation (~$0.035–$0.045/kWh) for systems larger than 10 kW. This means a 9 kW system earns 3× more per exported kWh than an 11 kW system in GP territory. Always design Georgia Power systems to produce 90–95% of your annual usage without exceeding 10 kW installed capacity.

Southeast Solar Guide 2026: Florida, Georgia, North Carolina, South Carolina, Virginia & Tennessee Compared

Q: Is solar worth it in Tennessee in 2026?

Tennessee solar is challenging due to the TVA Green Power Provider (GPP) structure: TVA pays only ~$0.048/kWh for solar exports vs. retail rates of $0.115–$0.125/kWh, and adds a mandatory $15.64/month ($188/year) Power Service Connection fee permanently. Standard paybacks are 14–18 years. However, Energy Community buyers in eastern Tennessee coal counties (Anderson, Campbell, Claiborne) qualify for the 40% ITC and can achieve 11–13 year paybacks with battery storage and self-consumption optimization.

The Southeast United States is one of America's fastest-growing solar regions — combining strong sun resources with a patchwork of state incentives that range from outstanding (South Carolina's 25% state tax credit) to challenging (Tennessee's TVA Green Power Provider structure). But "Southeast solar" is not a single market. A homeowner in Charleston, SC and a homeowner 200 miles away in Atlanta, GA face completely different financial outcomes from identical solar systems.

This guide compares the six major Southeast solar markets side by side, so you can understand exactly what you're working with — whether you're choosing between properties, helping a family member in another state, or comparing installer quotes across state lines.

The Southeast Solar Market at a Glance

The Southeast gets an excellent solar resource — 4.5 to 5.5 peak sun hours per day across most of the region, comparable to the southwestern United States in terms of annual production. The challenge is incentive structure: most Southeast states lack the robust state-level programs found in the Northeast, creating widely variable economics.

6-State Comparison Table (2026)

State	Avg Peak Sun Hours/Day	Key State Incentive	Net Metering Type	Standard Payback	10 kW Net System Cost
South Carolina	5.0–5.3	25% state income tax credit (up to $3,500/yr)	Retail rate, <20 kW	7–10 years	~$16,500
North Carolina	4.8–5.2	Energy Community 40% ITC in coal counties	Retail rate (HB 589)	9–12 years	~$18,600
Virginia	4.5–5.0	Energy Community 40% ITC in SW coal counties	Retail rate (VCEA-protected)	10–12 years	~$19,500
Florida	5.0–5.5	Property tax exemption + sales tax exemption	Retail rate (legislative review 2027)	9–13 years	~$18,000
Georgia	4.9–5.3	Property tax exemption	Retail ≤10 kW / avoided cost >10 kW	10–14 years	~$19,000
Tennessee	4.8–5.2	None (TVA structure)	TVA GPP ~$0.048/kWh + $15.64/month fee	14–18 years	~$21,000+

Net system costs after 30% federal ITC. SC includes partial state credit stack. All assume 9–10 kW system at $2.80–$3.00/W installed.

Bottom Line at a Glance: South Carolina is the Southeast's standout for most buyers. North Carolina is the best large market. Tennessee is the most challenging. Florida, Georgia, and Virginia fall in the middle depending on your specific utility and county.

South Carolina: The Southeast's Best Solar Incentive Stack

Verdict: Southeast's #1 state for solar economics for most buyers

South Carolina has the most generous solar incentive in the entire Southeast: a 25% state income tax credit (SC Code § 12-6-3587) with a $3,500/year cap, fully stacking with the 30% federal ITC. This credit is calculated on the full gross cost of the system — not reduced by the federal ITC — so the two credits add without reducing each other's basis.

South Carolina's Incentive Stack

Federal ITC: 30% of full system cost (40% in qualifying Energy Community census tracts)
SC 25% state credit: Up to $3,500/year, 10-year carry-forward
Property tax exemption: SC Code § 12-37-3135 — 100% exemption on added home value from solar
Net metering: Retail rate under 20 kW for all major utilities (Dominion Energy SC, Duke Energy Carolinas, Duke Energy Progress, Santee Cooper)
Sales tax: No exemption (SC's gap vs. GA/FL/NC)

South Carolina Worked Example

A Charleston homeowner installs a 9 kW system at $28,000 gross:

Federal ITC (30%): −$8,400
SC 25% credit Year 1: −$3,500 (Year 2: −$3,500, total 2 years: −$7,000)
Net cost over 2 years: ~$12,600
Annual electricity savings at $0.13/kWh and 4.5–5.0 PSH: ~$1,540/year
Simple payback: ~8.2 years (including full state credit stack)
25-year net savings: ~$26,000+

Columbia, SC homeowners with Duke Energy Progress see similar results: 8–10 year paybacks after the full credit stack. For buyers who have sufficient state tax liability to use the full credit quickly, SC is the strongest Southeast solar market.

SC Consumer Protection Note: If you lease solar or use a PPA, you lose the state income tax credit. Only system owners (cash purchase or solar loan) receive the 25% state credit. See the solar lease vs. purchase guide before deciding.

For full SC program details, see the South Carolina Solar Incentives Guide 2026.

North Carolina: America's Solar Powerhouse

Verdict: Southeast's #2 state — strongest large-market solar economics

North Carolina is the #3 solar state in the United States by installed capacity and generates more solar energy per capita than most Southern states. Its incentive advantage comes primarily from retail-rate net metering protected under HB 589 through at least 2027, combined with the 40% Energy Community ITC in Appalachian coal counties that covers much of western NC.

North Carolina's Incentive Stack

Federal ITC: 30% of full system cost; 40% in coal-county Energy Community zones (Rutherford, McDowell, Alexander, Wilkes, and surrounding western NC counties)
Property tax exclusion: G.S. § 105-277.3 — 80% of added solar value excluded (saves $2,880–$4,800+ over 20 years)
Partial sales tax exemption: Panels and inverters exempt; racking and labor taxable
Net metering: Retail rate under HB 589 for Duke Energy Carolinas, Duke Energy Progress, and Dominion Energy NC. Critical: annual true-up on April 1 — excess generation at year-end is credited at avoided cost (~$0.03–$0.04/kWh), not retail. Avoid oversizing by more than 5–10%.
NC GreenPower: Voluntary REC payments (~$0.005/kWh) — minor but real income for interested buyers

North Carolina Worked Examples

Charlotte (Duke Energy Carolinas, 30% ITC):

10 kW system at $30,000 gross
Federal ITC (30%): −$9,000
Net cost: ~$21,000
Annual savings at $0.12/kWh (Duke rate), 4.9 PSH: ~$1,870/year
Payback: ~11.2 years; 25-year net savings: ~$24,800

Rutherford County (Energy Community, 40% ITC):

Same 10 kW system, 40% ITC: −$12,000
Net cost: ~$18,000
Payback: ~9.6 years; 25-year net savings: ~$27,800

HB 589 Net Metering — The Critical 2027 Risk

NC's net metering is protected by HB 589 through at least 2027, after which the NC Utilities Commission will review the structure. This is a real policy risk for buyers. Current buyers who install before the review receive grandfathering that may lock in retail-rate treatment longer. Installing now vs. waiting is a legitimate timing consideration.

For full NC program details, see the North Carolina Solar Incentives Guide 2026.

Virginia: VCEA-Protected Net Metering and Rapid Growth

Verdict: Southeast's #3 state — legislative stability makes VA a strong long-term investment

Virginia's solar market has exploded under the Virginia Clean Economy Act (VCEA), which protects retail-rate net metering and sets a 100% clean energy mandate by 2045 for Dominion Energy and Appalachian Power (AEP). The VCEA protection is legislative (unlike California's regulatory NEM 3.0 change), making Virginia's net metering among the most stable in the Southeast.

Virginia's Incentive Stack

Federal ITC: 30% of full system cost; 40% in Southwest Virginia Energy Community coal counties (Buchanan, Wise, Dickenson, Tazewell, Lee, Scott, Russell, and surrounding area — one of the densest Energy Community concentrations in the nation)
Property tax exclusion: Code of Virginia § 58.1-3661 — 100% exemption on added solar value (saves $3,100–$4,800 over 20 years depending on county)
Limited sales tax exemption: Residential solar equipment exempt from the 5.3% state sales tax — saves $520–$740 on a typical 10 kW system
Net metering: Dominion Energy retail-rate NEM protected by VCEA through at least 2028; Appalachian Power (AEP) similar protection in SW VA. Annual April true-up; excess credited at avoided cost. Size to 90–95% offset.
Virginia Solar for All: IRA-funded program delivering free solar to income-qualified households. Applications open through approved installers.

Virginia Worked Example

Fairfax County (Dominion Energy, 30% ITC):

10 kW system at $32,000 gross
Federal ITC (30%): −$9,600
Net cost: ~$22,400
Annual savings at $0.125/kWh, 4.7 PSH: ~$1,880/year
Property tax exclusion NPV: ~$3,200 (20 years, 1.0% Fairfax rate)
Effective payback: ~10.2 years; 25-year net savings: ~$24,600

Wise County (Energy Community, 40% ITC):

Same system, 40% ITC: −$12,800
Net cost: ~$19,200
Payback: ~8.8 years; 25-year net savings: ~$27,800

Note: Northern Virginia (Fairfax, Arlington, Loudoun) has the state's best economics due to high Dominion rates ($0.12–$0.13/kWh) and strong sun resource (4.8–5.0 PSH/day in summer). Southwest Virginia buyers in Energy Community zones gain significantly from the 40% ITC bonus.

For full VA program details, see the Virginia Solar Incentives Guide 2026.

Florida: Strong Sun, Solid Exemptions, Legislative Caution

Verdict: Southeast's #4 state — excellent sun resource, key legislative risk to monitor

Florida is the #3 solar market nationally by annual installations, driven by 5.0–5.5 peak sun hours per day, a growing climate awareness among homeowners, and two valuable exemptions: a 100% property tax exemption and a full sales tax exemption on solar equipment. However, Florida's net metering faces a legislative review that makes 2026 timing genuinely important for buyers.

Florida's Incentive Stack

Federal ITC: 30% of full system cost (40% in Energy Community zones)
Property tax exemption: § 196.182 — 100% of added solar value excluded from property assessment for the life of the system. Worth $5,000–$10,000 over 20 years at Florida's average 0.9% property tax rate on higher-value homes.
Sales tax exemption: § 212.08(7)(hh) — 6% state sales tax + applicable county surtax on solar equipment exempt. Saves $1,200–$2,400 on a typical system.
Net metering: Retail-rate net metering legislatively mandated. Critical risk: Florida legislators have repeatedly tried to weaken net metering. Current law is in place through at least 2027 but the political landscape is uncertain. Installing in 2026 locks in retail-rate treatment for current policy; future changes may not apply retroactively.
No state income tax credit: Florida has no state income tax — there is no state solar tax credit. Ignore any installer marketing that implies otherwise.

Florida Worked Example

Tampa (Duke Energy Florida, 30% ITC):

10 kW system at $29,000 gross
Federal ITC (30%): −$8,700
Sales tax exemption benefit: ~$1,800 (not a credit — equipment just costs less)
Net cost: ~$20,300
Annual savings at $0.12/kWh (Duke FL), 5.1 PSH: ~$2,050/year
Simple payback: ~9.9 years; 25-year net savings: ~$30,800

Miami (FPL, high-rate territory):

10 kW system at $29,000 gross, FPL rates $0.13–$0.14/kWh
Net cost: ~$20,300
Annual savings: ~$2,200/year
Payback: ~9.2 years; 25-year net savings: ~$34,700

Hurricane resilience note: In hurricane-prone areas (South FL, Tampa Bay, Jacksonville coast), adding battery storage provides critical backup power. The 30% ITC applies to battery storage, and CA SGIP-style programs don't exist in FL — but the personal value of backup power during multi-day outages can be significant. See the solar battery backup vs. generator guide for backup power planning.

For full FL program details, see the Florida Solar Incentives Guide 2026.

Georgia: The 10 kW Threshold Every Buyer Must Know

Verdict: Southeast's #5 state — viable market, but Georgia Power's 10 kW threshold is the most important fact for GA buyers

Georgia is the #9 solar market nationally but has one of the Southeast's most restrictive net metering structures for larger systems. Understanding the Georgia Power threshold is more important for GA buyers than any incentive discussion.

Georgia's Incentive Stack

Federal ITC: 30% of full system cost; 40% in Energy Community zones (Jefferson County/metro Augusta, Walker County/Chattanooga metro, Etowah County/Gadsden area, Carroll County/West Atlanta metro, and others)
Property tax exemption: O.C.G.A. § 48-5-41 — full exemption on added solar value for all property types
No state income tax credit: Georgia eliminated its state solar credit years ago. Do not believe installer marketing claiming a "Georgia solar tax credit."
No sales tax exemption: Georgia's 4% state sales tax + county taxes apply to solar equipment — adds $1,000–$2,000 to effective cost vs. FL/NC/SC where exemptions exist.

The Georgia Power 10 kW Net Metering Rule — Critical Consumer Protection

This is the most important fact for any Georgia buyer in Georgia Power territory:

Systems ≤ 10 kW: Retail-rate net metering (~$0.12/kWh for exported power)
Systems > 10 kW: Avoided-cost compensation (~$0.035–$0.045/kWh for exported power — less than 1/3 of retail)

This means a homeowner who oversizes to 11–12 kW instead of 10 kW gets 3× less credit for every kWh they export. The practical implication: design Georgia Power systems to produce 90–95% of your annual usage and never exceed 10 kW installed capacity unless you plan to add battery storage to capture the export you'd otherwise lose.

The 40+ independent EMC (electric membership cooperative) utilities in rural Georgia have individual policies — some offer retail net metering, others don't. Always verify your specific co-op's policy before purchasing.

Georgia Worked Example

Atlanta (Georgia Power, 30% ITC, right-sized at 9 kW):

9 kW system at $27,000 gross
Federal ITC (30%): −$8,100
Net cost: ~$18,900
Annual savings at $0.12/kWh (GP rate), 5.0 PSH, 90% self-consumption: ~$1,700/year
Payback: ~11.1 years; 25-year net savings: ~$23,600

Jefferson County Energy Community (40% ITC):

Same system, 40% ITC: −$10,800
Net cost: ~$16,200
Payback: ~9.5 years; 25-year net savings: ~$26,300

For full GA program details, see the Georgia Solar Incentives Guide 2026.

Tennessee: Understanding the TVA Structure Before You Sign

Verdict: Southeast's #6 state — the most challenging Southeast market; self-consumption design is essential

Tennessee is the only Southeast state where the solar economics are fundamentally shaped not by net metering but by the TVA Green Power Providers (GPP) program — a structure that is widely misrepresented by solar installers and that most Tennessee buyers don't fully understand before signing contracts.

Tennessee's Incentive Structure

Federal ITC: 30% of full system cost; 40% in Energy Community zones (Anderson County/Oak Ridge, Campbell County, Claiborne County, Morgan County, Scott County, Sequatchie County in eastern Tennessee)
No state income tax credit: Tennessee has no state income tax — no state solar credit exists.
No property tax exemption: Tennessee does not exempt added solar value from property taxes.
No sales tax exemption: Tennessee's 7% state sales tax applies — plus local rates of 2.25–2.75% for a combined rate of 9.25–9.75%.

TVA Green Power Providers — What You Actually Get

In TVA territory (which covers most of Tennessee through Local Power Companies/LPCs), solar works like this:

Your system produces solar electricity
Your LPC pays you ~$0.048/kWh for every kWh your system generates (including what you self-consume, in most LPC programs)
Your LPC charges you the full retail rate (~$0.115–$0.125/kWh) for every kWh you consume from the grid
Your LPC charges a mandatory Power Service Connection fee of $15.64/month permanently, as long as you have solar

This is NOT net metering. The $15.64/month fee (~$188/year) adds to the effective cost of your system and must be factored into payback calculations. Most installer quotes omit this fee entirely.

The self-consumption imperative: Unlike net metering states where exported power earns retail-rate credit, in TVA territory each kWh you produce and immediately consume is worth ~$0.115/kWh (avoided grid purchase), but each kWh you export earns only $0.048/kWh. Designing systems for maximum self-consumption — properly sized, scheduled to match peak daytime loads, potentially paired with battery storage — is more important in Tennessee than anywhere else in the Southeast.

Tennessee Worked Example

Nashville (Nashville Electric Service, 30% ITC):

9 kW system at $27,000 gross
Federal ITC (30%): −$8,100
Net cost: ~$18,900
TVA GPP income (full production at $0.048/kWh): ~$900/year
Grid savings from self-consumed power (~40%): ~$580/year
PSC fee: −$188/year
Net annual benefit: ~$1,292/year
Payback: ~14.6 years (vs. ~9 years in SC or NC)

Anderson County Energy Community (40% ITC):

Same system, 40% ITC: −$10,800; net cost: ~$16,200
Payback: ~12.5 years — meaningfully better, but still longer than most SE states

Battery storage significantly improves Tennessee economics: With a battery, you shift morning and evening loads to solar self-consumption, increasing the effective value per kWh from $0.048 to $0.115+. A well-designed 9 kW + 13.5 kWh battery system in Nashville can achieve payback in 11–13 years including battery cost and 30% ITC on the battery.

For full TN program details, see the Tennessee Solar Incentives Guide 2026.

Energy Community 40% ITC Zones in the Southeast

The Energy Community bonus ITC (40% instead of 30%) is one of the most significant but overlooked solar incentives in the Southeast. Many buyers don't know they qualify.

Energy Community zones in the Southeast include census tracts meeting one of these criteria:

Coal community: Located in, or adjacent to, a census tract with a coal mine that closed after 1999, or a coal-fired power plant that retired after 2009
Fossil fuel employment community: Statistical area with 0.17%+ direct employment or 25%+ local tax revenue from fossil fuel industries

High-density Energy Community zones by state:

State	Notable Energy Community Areas
Virginia	Buchanan, Wise, Dickenson, Tazewell, Lee, Scott, Russell counties (SW VA coal belt — most of SW VA qualifies)
North Carolina	Western NC coal counties (Rutherford, McDowell, Alexander, Wilkes and surrounding areas)
Tennessee	Anderson, Campbell, Claiborne, Morgan, Scott, Sequatchie counties (eastern TN)
Georgia	Jefferson County (Augusta metro), Walker County (Chattanooga area), Etowah, Carroll counties
South Carolina	Select Upstate SC counties — verify via IRS Energy Community mapper
Florida	Selected industrial/historic fossil fuel counties — verify site-specifically

How to verify your address: Use the IRS Energy Community eligibility mapper at the IRS website or consult your installer. Energy Community eligibility applies at the census tract level, so your neighbor might qualify even if you don't (or vice versa).

The 40% ITC on a $28,000 system is $11,200 vs. $8,400 at 30% — a $2,800 difference. This significantly changes payback calculations, especially in lower-incentive states like Georgia, Tennessee, and Virginia's SW coal counties.

Southeast Regional Comparison: Net Metering Policy Map

Net metering structure is the single most consequential variable for Southeast solar buyers after state incentives. Here's where each state stands:

State	Net Metering Type	Export Rate	Policy Stability	Annual True-Up?
South Carolina	Retail rate	~$0.13/kWh	Stable (PSC-mandated)	Yes — end of April
North Carolina	Retail rate (HB 589)	~$0.12/kWh	Review in 2027	Yes — April 1
Virginia	Retail rate (VCEA)	~$0.125/kWh	Strong (legislative)	Yes — April
Florida	Retail rate (FPL/Duke/TECO)	~$0.12–0.14/kWh	At-risk (legislative)	Yes — annual
Georgia	Retail ≤10 kW; Avoided >10 kW	$0.12 or $0.035	Stable (PSC-mandated)	Yes — annual
Tennessee	TVA GPP buyback, NOT net metering	$0.048/kWh	Stable (TVA program)	No — monthly settlement

Key consumer protection insights:

Never oversize in GA (above 10 kW for GP customers), NC, VA, or FL beyond 90–95% annual offset — excess at true-up is credited at avoided cost
Tennessee is not net metering — understand the GPP structure and $15.64/month fee before signing any contract
Virginia's VCEA protection makes it the most policy-stable Southeast net metering environment
Florida's legislative risk makes 2026 timing relatively attractive — current buyers lock in existing retail-rate treatment

Southeast Ranked: Which State Is Best for Solar?

#1 South Carolina

SC wins on raw financial incentives — the 25% state income tax credit (up to $3,500/year) stacking with the 30% federal ITC delivers the fastest paybacks in the Southeast for most buyers. Charleston and Columbia paybacks of 8–10 years are the best in the region. If you have sufficient SC state tax liability and own your home, SC is the clear Southeast leader.

Limitation: Insufficient state tax liability limits the credit's value. The 10-year carry-forward helps, but buyers with very low state tax bills may not fully capture the credit.

#2 North Carolina

NC is the best large-market solar state in the Southeast — the #3 solar state nationally with strong retail-rate net metering under HB 589 and excellent Energy Community ITC zones in western NC. Charlotte, Raleigh, and Asheville all support economically solid solar investments with 9–12 year paybacks.

Limitation: HB 589 review in 2027 creates a genuine policy risk. Installing now provides some grandfathering protection.

#3 Virginia

VCEA-protected net metering (the strongest legislative protection in the Southeast) and dense Energy Community zones in Southwest Virginia make VA a strong long-term investment. Northern Virginia's high Dominion rates ($0.12–$0.13/kWh) improve economics for Northern VA buyers.

Limitation: Higher average installed costs than other Southeast states and slightly longer paybacks than SC/NC in standard (non-Energy-Community) locations.

#4 Florida

Excellent sun resource (5.0–5.5 PSH/day), a full sales tax exemption, and a lifetime property tax exemption make Florida financially solid. Miami/FPL territory buyers with high electricity bills see 9-year paybacks.

Limitation: Legislative risk to net metering is the biggest concern. Future policy changes are possible.

#5 Georgia

Georgia's sun resource and Energy Community ITC zones make solar viable, but the 10 kW Georgia Power threshold is a significant constraint. Properly sized systems (≤10 kW for GP customers) produce 10–12 year paybacks; oversized or Energy Community buyers do better.

Limitation: The 10 kW GP threshold, no state credit, and no sales tax exemption place GA below SC/NC/VA/FL for most buyers. Rural EMC territory varies widely.

#6 Tennessee

Tennessee's TVA structure, mandatory $15.64/month Power Service Connection fee, and lack of any state incentives make it the most challenging Southeast solar market. Paybacks of 14–18 years are common without battery storage or Energy Community status.

Exceptions: Energy Community buyers in eastern Tennessee and buyers who optimize for self-consumption (battery storage, high daytime load shifting) can achieve 11–13 year paybacks — still longer than most Southeast states, but viable.

Southeast Solar Shopping Guide: How to Proceed

Regardless of which Southeast state you're in, follow these steps before signing:

Verify Energy Community eligibility — Enter your address in the IRS EC mapper. A 40% ITC vs. 30% ITC is $2,800 on a $28,000 system.
Get your utility's specific net metering policy in writing — In GA: determine if you're in GP, EMC, or municipal territory and ask about the 10 kW threshold. In TN: confirm GPP rates and the $15.64/month PSC fee.
Run your own numbers — Use the Solar ROI Calculator with your state, utility rate, and estimated kWh usage. Don't rely solely on installer production estimates.
Get at least 3 quotes — Use the how to compare solar quotes guide to evaluate proposals side by side.
Check NABCEP certification — In all Southeast states, licensed contractors are required. Check the how to choose a solar installer guide for vetting steps.
Size to 90–95% offset — In all Southeast states with annual true-up (NC, VA, FL, GA, SC), excess end-of-year credit is settled at avoided cost. Oversizing costs money.
Start with the Solar System Designer — Use the Solar System Designer to estimate your system size before meeting with installers, so you can evaluate their proposals against an independent baseline.

Frequently Asked Questions

Which Southeast state has the best solar incentives?

South Carolina leads the Southeast due to its unique 25% state income tax credit (up to $3,500/year, 10-year carry-forward) stacking with the 30% federal ITC. This combination can reduce a 9 kW system's net cost to $12,000–$14,000 after incentives, producing 7–10 year paybacks. North Carolina is the best large market for buyers who don't qualify for the SC state credit. See the Southeast Solar Guide 2026 for a complete 6-state comparison.

Is Tennessee solar worth it in 2026?

Tennessee solar is challenging but viable in the right circumstances. The TVA Green Power Provider structure pays ~$0.048/kWh — far less than retail electricity rates — and adds a mandatory $15.64/month Power Service Connection fee permanently. Standard paybacks are 14–18 years. However, Energy Community buyers in eastern Tennessee coal counties qualify for the 40% federal ITC, and combining solar with battery storage for self-consumption optimization reduces payback to 11–13 years. See the Tennessee Solar Incentives Guide 2026 for full details.

What is the Georgia Power 10 kW solar threshold?

Georgia Power customers receive retail-rate net metering credit (~$0.12/kWh) for systems up to 10 kW, but receive only avoided-cost compensation (~$0.035–$0.045/kWh) for systems larger than 10 kW. This means a Georgia Power customer with a 9 kW system earns 3× more per exported kWh than a customer with an 11 kW system. The practical rule: design Georgia Power systems to produce 90–95% of annual usage without exceeding 10 kW installed capacity. See the Georgia Solar Incentives Guide 2026.

Is Florida net metering at risk?

Florida's retail-rate net metering is legislatively mandated, but Florida legislators have repeatedly attempted to weaken or eliminate it. Current law is in place through at least 2027. Buyers who install in 2026 may receive some grandfathering protection from future policy changes, though this is not guaranteed. The property tax exemption and sales tax exemption, by contrast, are structurally stable. See the Florida Solar Incentives Guide 2026 for current policy status.

Does the Energy Community 40% ITC apply in the Southeast?

Yes — the Energy Community 40% ITC applies throughout much of the Southeast, particularly in Appalachian coal communities. Virginia's Southwest coal counties (Buchanan, Wise, Dickenson, Tazewell) have extremely dense Energy Community coverage. Western North Carolina coal counties (Rutherford, McDowell), eastern Tennessee coal communities (Anderson, Campbell, Claiborne), and select Georgia industrial counties all qualify. Use the IRS Energy Community mapper to check your specific address before getting quotes.
